Why is the value determined by what libc supports? The definition from the 
standard is:

  If this symbol is defined, then every character in the Unicode required set, 
when stored in an
  object of type wchar_t, has the same value as the short identifier of that 
character.

That doesn't seem to imply anything about the library, just the size of 
`wchar_t`.
